ig. 7 is an enlarged vertical section of Be it known that I, JAMES A. NORTON, a citizen of the United`- States, yresiding A at Odebolt, in the county of Sac vand Statey of Iowa,V have invented certain new and useful Improvements inPumps7 of `which the'following is a specification;

` This invention relates to pumps and particularly to the operating means therefor.

@ne object is to provide a means for operating pumps of thecharacter employed in raising water from deep wells or mining or irrigation operations where a continuous stream or volume of water is generally desirable. 4

`Another object resides in the provision of means operable to operate the pump in which 'the means for accomplishing the purpose performs its :functions with a minimum amount of power.

Another object ofthe invention is to provide a pump embodying means to temporai-ily 'relieve the load so as to facilitate starting the pump and which load relieving means may be subsequently operated so that the pump may liftl to .its full capacity.

With the above and other objects in view, the present'invention consists iny the combination and arrangement of parts hereinafter more fully described, `illustrated in the accompanying drawings, and particularly pointed out' in the appended claims, it being understood that changes may bemade in the form, size, proportion and minor ydetails without departing from the spirit or sacrificing any of the advantages of the invention.

VReferring now more particularly to th accompanyingdrawings, the reference char- -acter 8. indicatesfa base whichY may be composed of any suitable material and of any suitable-formation and which is provided with apertures 9, 10 land 11 for a purpose presently explained. y

A pump cylinder 12 is mounted in any Y suitable Vmanner below the base S. This pump cylinder 12 is preferablyL solidI at its upper end, as indicated at'13, and at its upper end exteriorly 'screw threaded for working iit` with the interiorly screw threaded boss 14 on the under side of the base S, said solid portion 13 having a bore 15 alining with the aforesaid aperture 11 of thebase.

`A discharge Outlet or spout 16 extends l laterally yfrom the pump cylinder at the outerv endr thereof and preferably immediately below the solid portion 13 of thek cylinder. The pump cylinder at a point adjacent the lower end thereof is provided with openings 17, these openings being of any suitable form but, `as shown, being in the form of relatively short spaced slots.

These o eninos are arraned oreferabl slightly above the water line and are normally closed by a sleevey 18 which` slidably embraces the pump cylinder. An arm 19 is turn is connected with the offset end 20 of `a controlling bar 21 slidable through a slot v22 in the base 8. Y

Thecontrolling bar 21 is provided with teeth 23 with which coacts a spring controlled pivoted dog 24 mounted on the base 8 so as tohold the controlling bar 21 andy 4consequently the sleeve 18 in adjusted positions with relation to the openings 17 in the pump cylinder. To facilitate operation of the controlling bar 21 the same may be provided with a suitable handle 25. The purpose yof sliding this sleeve over `and away.

piston is provided with suitable check Valves adapted to open and close upon the up and down strokes thereof. In the present in- Aconnected to the sleeve 18 and the arm in 52 positioned cio-axially in spaced relation to leach other vThe upper end stance each piston is provided with a transverse web 29 at its upper end to which flap valves 30, preferably of segmental shape, are hingedly connected land whichl at their free edgesV rest preferably on the upper'end of the respective piston. These pistons are adapted to reciprocate in paths which overf lap eachother -and in circles'an equal dis-A At alltance apart,A say for' instance, 1200. times at least one of the pistons will be on the upstroke and the lowerrnost piston 28`is located below-the aforesaid openings 17 traveling below the surface of the water.

The lowermost piston 28 is supported in the'pump cylinder in anyjsuitable manner but, as" shown, itissupported on parallel rods 31y and, 32 arranged parallel with the vrpump cylinder and eXteriorly thereof, reciprocating through suitable guides 33 and 34, respectively, projecting from the lower end ofthe pump cylinder. The lower .ends of these parallely rods 31 and 32 are yconnected by a cross piece 35 in any, suitable manner and to vthis cross piece 35l is a short supporting upright 36 to which the lowermost pis-v ton 28 is connected. The upper endsA of these rods 31 and 32 reciprocateithrough the opposite apertures 9 and 10 in the base 8 and .at their upper ends rthe-y are connected in any suitable manner to the cross head 37 slidable on guide rods 40 andy-41, respectively, which are connected at their lower ends to the-base 8 and to a Vplatfor-m 42 supported above the base 8 by means of the upwardly converging supporting uprights143, preferably four in number. The cross head 37 has laterally directedarms 38v and 39 fo ra purpose presently explained.

The uppermost piston 26V is secured in any suitable manner to the lower end of a tubular pistonv rod 44 which reciprocates through the boreand apertures 15 and 11, respectively, of the solid 'portion-130i: the pump cylinder and the base 8, respectively, and freelyl through the aforesaid cross head 37. of said tubular piston rod is secured in any suitable manner to a cross lhead 45 slidably connected tothe aforesaid guide rods 40 andv 41 and provided with the laterally directed arms 46 and 47.

l The intermediate piston 27 is secured in any suitable manner to the vlower end of a pistoiirod 48 which reciprocatesrwithin the aforesaid tubularpiston rod 44 and is secured at its upper lend to a cross head 49 slidably yembracinglthe aforesaid guide rods 40 and 41, and provided with laterallydirected arms 50 and 51.A i

The 1piston operating means embodies among otherv characteristics three spur-rings above the platform 42. Each spur-'ring is inclosed 'within a suitable separate supporting housing 53 vconsisting of sections a and b which inclose the opposite Sides 'cross headl 475.

,respective 'spur-rings. y

The' spur-ringsv arer rotatable? .on roller bearings 56 interposedV between the annular shoulders 57 on the sides of the rings and 'the internal annular shoulders 58 formed on the housing sections. These housings may be mounted on suitable bases 59 and secured by means of bolts or otherwise on the platform 42 with each housing provided with a lateral extension 60 to the ,outer sides of which suitable covers y61 may be securedy by bolts 62 or otherwise. p

A drive shaft 63 is journaled in .bearings 64 formed in the lateral 'extensions .60 ofthe spur-ring housings and pinions 65 are keyed to this shaft 63,*one pinion located within each of the eXtensions60 for mesh with the respective spur-rings 52. p Y j The shaft 63 maybedriven through any suitable source of power. In the'v present embodiment of the invention,however,it is illustrated as being actuated by the combustion engine 66 mounted on a suitable support 67 secured to an extension 68 of the .platform 42. l l

Theuppermostcross head 49 has its laterally directed arms 50 Vand A51 connected by wrist pins 50A and 51 to tlievintermediate .spur-ring 52 on opposite sides of thelatter The pitman connections 71 and 72 are'connected at their lower ends to the arms 46 and 47 ofY 4the VPitman connections 73 `and 74 have l connections at'tlieirrlower ends with the arms 38 and 39 of the lowermost cross head 30 and at their upper ends they, are eccentrically connected by wrist pins 76 to the outer sides ofthe outer spur-rings52, being` positioned substantially 120"- from' both of the eccentric connections of the other ,pitmen with the It is evident that, when theiSleeve-lS is lifted to a position aboif'etheopenings17in the side walls ofA the pump cylinder, vthe load onV the lowermost yvalved. piston 28 will be considerably reduced because ofthe fact that these ,openings 17 are disposed .tionsoftlie aforesaid pitmeii l69 and 70 with .the intermediate spur-ring.
